Cloned food years from shelves
FDA approval spurs companies' hopes

SAN FRANCISCO -- Despite a government endorsement, food from cloned animals could take years to reach supermarket shelves.
But the backing does give hope to several struggling businesses that clone cows and pigs. The biotechnology companies believe ranchers, dairy producers and others now will be more willing to pay more than $16,000 per clone following last week's tentative approval by the Food and Drug Administration to use the technology to produce food.
Although no law bars cloned food, the companies have for the past three years voluntarily withheld sales of cloned-derived food pending the FDA review.
An 800-page FDA report concluded Thursday there is no difference between cloned and conventionally produced food. The FDA won't formally adopt its findings until early 2007, keeping the voluntary ban in place.
The initial milk, beef and pork products on the market likely won't come directly from cloned animals because of the technology's cost. Instead, ranchers are expected to pay to produce a "rock star" breeder that would produce valuable offspring for years to come.
The idea is to create exact genetic duplicates of animals that consistently produce superior offspring. Breeding today is as much art as science, and ranchers have no way of knowing if a particular cow will become steakhouse grade cuts or dog food.
Cloning aims to take much of that guesswork out of breeding by guaranteeing that offspring of cloned animals carry superior genetics that will fetch top prices.
But cloning breeders is one thing, watching them grow old enough to produce food is another. And once that happens, the cloning industry is also going to have to overcome consumer skepticism.
Mark Walton, president of the ViaGen Inc., said that it would take about five years for clone-derived food to hit the market.
"And it still we be relatively small numbers," he said. "For this to really take off, producers are going to have to see the animals out in the field."
ViaGen and others have been awaiting the FDA decision for four years, a period during which several rivals have gone out of business. ViaGen has survived because it's backed by a billionaire investor and has brought in revenue by cloning show horses and rodeo bulls.
The privately held company controls most of the field's key patents -- including the one granted to the creators of Dolly the sheep -- and is expected to benefit most from the FDA ruling.
ViaGen cloned 65 heads of cattle and five horses this year. With the FDA approval, the company hopes that some food producers will decide to clone some of their better animals in anticipation of cloning becoming widely accepted.
Critics of cloning say the verdict is still out on the safety of food from cloned animals, while others complain that cloning results in more deaths and deformed animals than other reproductive technologies.
Some surveys have shown people to be reluctant about eating food from cloned animals. In a September poll by the Pew Initiative on Food and Biotechnology, a nonpartisan research group, 64 percent said they were uncomfortable.
"It remains to be seen whether dairy farmers will choose to use it," said Connie Tipton, president of the International Dairy Foods Association. "There currently is no consumer benefit in milk from cloned cows."
The few companies such as ViaGen of Austin, Texas, and Cyagra of Elizabethtown, Pa., insist they can sway public sentiment. They argue that consumers may be confusing cloning with genetic engineering, a technology that has generated vocal opposition when applied to crops.
The companies liken cloning to now-common reproductive technologies such as in vitro fertilization and artificial insemination, both of which are often used to create elite animals that sell at a premium.
